<p>A multi-phase cemented ceramic material useful for metal working, including ferrous metals, titanium, aluminum and other metals. The material preferably has a microstructure which includes platelets, a range of grain sizes which yields superior hardness and other characteristics, and a low tungsten concentration within the binder phase. The preferred composition includes ultrafine WC, an ultrafine solid solution of (Ti, Ta, W)C, and a cobalt binder. Platelets are formed in situ, eliminating the need to add them during manufacture for improving toughness.</p> |
